If you just want an overunity experiment, then by all
means repeat (or have your university repeat) Bohren's
experiment, which gives 18 times as much energy out as you
put in. Does it every time, any time, anywhere.

See Craig F. Bohren, "How can a particle absorb more than the
light incident on it?" American Journal of Physics,
51(4), Apr. 1983, p. 323-327. Under nonlinear conditions, a
particle can absorb more energy than is in the light incident on it.
Metallic particles at ultraviolet frequencies are one class of such
particles and insulating particles at infrared frequencies are another.
See also H. Paul and R. Fischer, (Comment on “How can a particle
absorb more than the light incident on it?’},” Am. J. Phys.,
51(4), Apr. 1983, p. 327 which replicated the Bohren experiment
independently and validated its results.

Even in the standard literature, every generator puts out enormously
more energy than one inputs to its shaft to "drive it".

From the terminals there pours out two components of
energy flow; (1) the Poynting component, which is the tiny little bit of
that flow that skips the surface of the attached circuit, strikes the
surface charges, and gets diverged into the conductors to power up the
electrons. Rather like sticking your hand out of a moving
automobile, to divert some of the passing air stream into the car.
(2) the enormous Heaviside nondiverged component, which is an enormous
energy flow filling all space around the wires, and missing the circuit
entirely and just wasted. E.g., see John D. Kraus, Electromagnetics,
Fourth Edn., McGraw-Hill, New York, 1992. Figure 12-60, a
and b, p. 578 shows a
good drawing of the huge energy flow filling all space around the
conductors, with almost all of it not intercepted and thus
not diverged into the circuit to power it, but just "wasted."
Kraus' contours are experimental measurements; it shows you how much
power can be intercepted at any point in that space, by a unit point
static charge. If you place 100 unit point static charges there,
you will catch 100 times as much energy as Kraus' number on the contour.

So any average experimenter and any laboratory can easily show --
experimentally and theoretically -- that there is enormous energy
pouring out of the terminals of every battery and generator. Well, why
has your university not made you aware that every EM circuit and every
generator and every battery is now and always has been an overunity
energy converter, outputting vastly more energy from its terminals than
we input to its shaft or that the battery possesses in chemical energy?

Why do they not teach their student that, as energy transducers,
batteries and generators and all dipoles already exhibit
COP>>1.0???

Why are they not voraciously pursuing this, to develop and build
systems catching and using more of it?

When do you think they will get around to pursuing it, and quickly
producing and marketing the overunity systems they easily could???

In short, the Bohren experiment is a bona fide, certified, overunity
experiment. So what has been done with it commercially?

Nothing.

You see my point. Infrared is heat, e.g., and so one can use
that process to get about 18 times more heat energy than one inputs,
under the proper circumstances. So why is your university not
doing it in their technical departments?

Why have they not told you about it?

Why is the electrical power industry not using something modified
from that to reduce the energy input to their heaters under the boilers
making the steam to drive the steam generators that are turning the
shafts of their generators?

Hey, there's another free one for you. With effort, such a
system could in fact be developed.
